ENZYME entry: EC 2.7.4.23

PURL: https://purl.expasy.org/enzyme/EC/2.7.4.23
Accepted Name
ribose 1,5-bisphosphate phosphokinase
Alternative Name(s)
ribose 1,5-bisphosphokinase
Reaction catalysed
alpha-D-ribose 1,5-bisphosphate + ATP = 5-phospho-alpha-D-ribose 1-diphosphate + ADP
Comment(s)
  • This enzyme, found in NAD suppression mutants of Escherichia coli, synthesizes 5-phospho-alpha-D-ribose 1-diphosphate (PRPP) without the participation of EC 2.7.6.1.
  • Ribose, ribose 1-phosphate and ribose 5-phosphate are not substrates, and GTP cannot act as a phosphate donor.
